I wanted to share a story with everyone. I was off-roading in Florida in my 78 Bronco 35" tires 3 inch Rancho suspension lift. We were about 3 miles in the woods when a branch sheered off my valve stem on my RF tire. This turned out to be a 6 hour headache we had to call my buddy to come get the tire my spare was the stock size 31 inch. By the time it was fixed and I got out of the woods my play day was over. I went online that night and found these replacement valve stems called surevalves. I ordered a set and had them installed they kick A**. I found them at www.hcwsinc.com if anyone is interested. They were reasonably priced, also for $25 I could of saved a day of pain.  

Are they metal or what?
